Uh... is this supposed to be valid standalone C?

GCC says there are a bunch of undefined symbols, first one being "R" right in the beginning:

  typedef  unsigned  char u;
  u w,X,T,D[1<<16],t[]=R,U=255;

That's defined in Makefile

  • That is correct. It is cheating, but the judges let a small amount of it slide, especially if you come up with an amusing enough justification. I could not get it to fit otherwise!
